[問題]maxwell render

[chatho]

有無人用過/緊maxwell render?

雖然render的setting唔多，不過o的material要set得真就真系好花時間……
想問問有無一個standard的呢?

同埋唔知點解ren來ren去都勁大noise lor...開o左anti alising都系咁...

[h2o]

因為仲系 beta 版麻

其實仲有其他方法可以試下:
1. render time 可以 set 長d
2. object color 減下 saturation & luminance
3. outdoor 環境用 physical sky 會好過用 object or image,
indoor 環境則用skydome
4. 個 scene light source 多寡都有影響, 如果用 object 做 light emitter 就越少 face 越好
5. render 幅圖大一倍, degrain, 然後縮細

thz so much~
估唔到o的咁spend time 既renderer你都咁有研究wo
不過真系唔知佢用咩方法o黎做render...
完全唔同主流的renderer, o的photon map ar...final gather ar都唔鬼見哂...

[h2o]

個 theory 都幾"非一般" 架.... , 有時間我都可以講下既

不過我都系試左一兩日, 簡簡單單試下 cornell box, chrome ball 就算
咁多 noise, 等佢出多一兩個 version 先再試

You can go to Flamingo newsgroup and obtain some special solution as well, frankly speaking, I'm waiting for the official release as well, as the rendering principle is truly amazing and close to reality....for the grains...you can say it's close to high ISO films....

可以試試 FINALRENDER 渲染器 另外可不可以 多用中文和普通話？

[Siegfried]

I've tried it for a couple days, the grain is pretty unacceptable when rendering time is limited, but what attract me is the choice between inputing rendering time and sampling, so that you can actually limit the time spend on it.

The beta ver would be far better on rendering speed by 400%, I'll wait for that and give it a shot.

Yet, Maxwell didn't work when I render it in 4Kx3K px, dunno if it's my problem.

30 mins of grainy rendering. The center spot is an emitter.
The green zone are in glass material.
Result - No eye see.

[chatho]

Result - No eye see.

我見maxwell 個forum o的人個個o的圖ren廿個鍾都視作等閒事...
o個o的就 have see head 啦~

系咪maxwell render 可以render 到d 似高iso菲林的noise？
其他render engine 又如何呢!

[h2o]

noise 後期加都得, maxwell render d 圖想冇 noise 的話就幾難咯!

[S'tephen]

　
未用過maxwell render ，所以不會說！
但noise 後期方法有後期的味道，maxwell render 個味noise，我比較看好！

[Siegfried]

As I don't have "Neatimage", so please bear the noise.

Rendering time : 1h 10m
Px :1024 X 768
Shutter : 1/60
Aperture : f/12
Sampling Level : 15
Threads : 4
Bounce : 8
Sky Dome : 30 - RGB all 253
Additional Lighting : 1 Surface Light, Cool White, 200W.
Layer : All on
Burnt : 0.7
Gamma : 1.0

[Siegfried]

The beta verion is released, but there are still many bugs, especially to Rhino (OMG), material cannot be applied at all if you wanna run the rendering. Next Limit (NL) is gonna to upload the patch to fix the problem in these couple days.

In the mean time I'm running some comparison test on the time consumption. A challege to my office computer to keep running for several days.

The effect of time in reducing noise.
